IMPROVEMENT m RUDDEFi-INDICATING APPARATUS FOR vEfssELs.

Specification forming part of Letters Patent No. 174,186 ,dated February29, 1876; application filed December 21, 1875. v

To all whom it may concern:

Be it known that I, J USTUS ALBERT Buria- BAGH, of Olaptomin the countyof Middlesex, England, have invented a new and useful Improvement inApparatus for Preventing Collisions at Sea; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawing, forming a part of thisspecisition of the rudder shown in section., Fig. 2

is a plan view of the apparatus, in this view the lantern being shown insection.

In these figures, a is the rudder-post; b, an arm thereon, to which isjointed a rod, 0, which passes to the fore part of the vessel,

' being surrounded by a fixed stout tube, d, to

prevent its being injured orimpeded in its operation. For vessels ofconsiderable length the friction upon the rod may be reduced bysupporting itupon pulleys. The forward end of the rod is coupled to alever-arm, c, or an axis, f. This arm may either project upward from theaxis, as shown, or downward, so as to bring the rods 0 close down. tothe bed-plate of the frame by which 'the axis f is carried. On this axisis anotherarm, 9, which, by a vertical rod, h, isconnected to a slide,is, which can move up and down in the interior of the lamp-case l.Thislampcase has a circular opening, 1, extending nearly all around,through which the light is to be exhibited. The slide 70 has an openworkframe in which are carried two colored glasses, m, red and green, oneabove the other.

When the rudder is in a line with the keel or midship, the slidecarrying the colored glasses will be in its central position, and anequal amount of light of each color will be exhibited through theopening Z; but when is and glasses carried by it, the axis f hasattached to it a weighted arm, n.

In order that the movement of the rudder may be denoted equally well atdaytime as at night, the slide is is formed with an arm, 0,

standing out from it, which passes through a vertical slot in thelamp-casing.

To the back of the lamp-casingtl1at.is, to the side away from the bow ofthe vessel-is jointed a lever, 19, one arm of which carries a red flagand the other a green. The arm 0, projecting from the lamp-slide, isjointed to one arm of this'lever in such a manner that when the slide'israised or lowered the lever 10 will be turned on its axis, and eitherthe red flag will be raised and the green lowered, or vice versa.

Another arrangement for raising and lowering flags of two difi'erentcolors, in accordance with the movements of the rudder is shown at Fig.3. In this case a lever, p, is jointed to the back of the lamp-casing,and is coupled by a link to the sliding rod h. Each end of the lever 19is connected by a rod to the short arm of a lever, r, the larger arm ofwhich carries a flag, as shown, so that, as the sliding rod h rises orfalls, in accordance with the move ment of the rudder, one flag will beraised and the other lowered.

Fig. 4 shows an arrangement in which the flag-signaling apparatus forindicating the position of the rudder at daytime is independent of thelamp, so that the lamp may be entirely removed when not required. Inthis arrangement, h is the upright sliding rod,

which is raised or lowered, as in the former arrangements, by an arm onthe axis f, and giving motion, by a link at its upper end, to an arm onthe axis f, and giving motion, by a link on its upper end, to an arm onan axis, 8, mounted in a suitable frame. On the axis are two longer armscarrying flags or colored disks, as shown. The rod h may also be formedwith an arm standing out from it at t, and having at its end a socket,into which a rod, in connection with the lamp-slide, may be dropped andsecured by a pin, a suitable stand being provided for the lamp to restupon. By this arrangement the lamp may be entirely removed, when the pinabove mentioned-is withdrawn.

Having thus desc edjmy invention, what 1 claim as new is 1. Thecombination, with the rudder-stem and suitable connecting mechanism, ofthe axis on its outer ends flags or signal-disks, as and Y for thepurpose described.

The above specification of my invention signed by me this 26th day ofOctober, 1875.
